A study of marital relationships in which one partner's sleeping and waking cycles differ from those of the other partner reveals that such couples share fewer activities with each other and have more violent arguments than do couples in a relationship in which both partners follow the same sleeping and waking patterns. Thus, mismatched sleeping and waking cycles can seriously jeopardize a marriage.

Which of the following, if true, most seriously weaken the argument above?

A. Married couples in which both spouses follow the same sleeping and waking patterns also occasionally have arguments that can jeopardize the couple's marriage.
B. The sleeping and waking cycles of individuals tend to vary from season to season.
C. The individuals who have sleeping and waking cycles that differ significantly from those of their spouses tend to argue little with colleagues at work.
D. People in unhappy marriages have been found to express hostility by adopting a different sleeping and waking cycle from that of their spouses.
E. According to a recent study, most people's sleeping and waking cycles can be controlled and modified easily.

答案A为什么不是正确选项呢?谢谢大家的帮忙！

我选D。

题干的结论是睡眠不同步导致婚姻破裂，D的解释是夫妻关系不好导致双方选择睡眠不同步，对得出结论的因果关系提出质疑。

A是睡眠同步的夫妻也会“偶尔”发生导致婚姻破裂的吵架，但并没有有效地削弱结论和得出结论的逻辑（睡眠不同步→婚姻破裂）。
